The SCT12A0 is a high efficiency, fully integrated synonous boost converter with a 13mΩ high-side MOSFET a 11mΩ low-side MOSFET, supporting 2.7V to 14V input voltage range up to 12-A switch current. The switch current limit can be adjusted with an external resistor. The device adapts constant off-time peak current control to provide fast transient response. An external compensation network allows flexibility setting loop dynamics to achieve optimal transient performance at different load conditions. Using MODE pin sets either Pulse Frequency Modulation (PFM) operation or forced Pulse Width Modulation (PWM) operation. The SCT12A0 monitors both output voltage feedback voltage to protect over-voltage condition. It features cycle-by-cycle peak current limit thermal shutdown protection when the device over loads current. SCT12A0 is available in a low-profile package DFN-20L 3.5mmx4.5mmx0.9mm with enhanced thermal power pad.
